Cu(OAc)2·H2O-Promoted Tandem β-Alkynyl Elimination of α- or β-Hydroxy Propargylic Alcohols and Homocoupling of the Resulting Alkynyl Species. (September 2013) - Xu, Xiangsheng
Α or β-hydroxy propargylic alcohols undergo tandem C(sp)–C(sp 3 ) bond cleavage via β-alkynyl elimination and homo-coupling of the resulted alkynyl species in the presence of Cu(OAc)2 ·H2 O to produce the corresponding hydroxycarbonyl compounds and 1, 3-butadiynes.
